1, the brightness
LED housing lights have a relatively brighter than traditional lights, thus they have different prices.
2, the antistatic ability
Antistatic ability LEDs, long life, and therefore higher prices. Usually static than 700V LED can be used for LED housing lights.
3, the wavelength
The same wavelength LED,? Same color, such as requiring the same? Color, the price is high. No the LED housing lights instrument manufacturer it is difficult to produce pure colors products.
4, the leakage current
LED is one-way conductive light, if the reverse current is called leakage, the leakage current of the LED, short life, low prices.
5, light-emitting angle
Different uses LED housing lights angle is not the same. Special light-emitting point of view, higher prices. If all diffusion angle, the higher prices.
6, the life
Different key to the quality of life, life light bad decision. Light decay, long life, long life and high price.
7, the LED chip
LED housing lights chip, different chips, the price difference. Chips more expensive in Japan, the United States, the Taiwan plant and the local Chinese manufacturers LED chip price is lower than the United States.
8, the chip size
The size of the chip to the side of the quality of large-chip LED housing lights (sometimes led high bay lights can be used for instead) is better than small chips. Prices are proportional to the chip size.
9, the colloid
Ordinary LED housing lights colloid general epoxy resin, plus a more expensive LED UV and fire retardant, high-quality outdoor LED lighting should be UV and fire.
